    Habit
    Perennial; caespitose. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms 70-100 cm long. Lateral branches lacking. Leaf-sheaths glabrous on surface. Ligule a fringe of hairs. Leaf-blades convolute; 15-30 cm long; 2-4 mm wide; coriaceous; stiff. Leaf-blade margins scabrous. Leaf-blade apex acute; pungent.
    Inflorescences
    Gynodioecious (male, in this context, indicating the bisexual state). Inflorescence a panicle. Panicle open; lanceolate, or ovate; 12-20 cm long. Panicle branches pilose. Spikelets solitary. Fertile spikelets pedicelled. Pedicels bearing a few hairs; hairy at tip. Male inflorescence bisexual similar to female; a panicle. Male spikelets resembling female.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 9-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 9-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes similar; shorter than spikelet, or reaching apex of florets; similar to fertile lemma in texture; gaping. Lower glume linear; 7-9 mm long; 0.8 length of upper glume; membranous; 1 -veined. Lower glume lateral veins absent. Upper glume subulate; 8-11 mm long; 1.6 length of adjacent fertile lemma; membranous; 1 -veined. Upper glume lateral veins absent.
    Florets
    Fertile florets female. Fertile lemma linear, or lanceolate; 5-7 mm long; membranous; without keel; 5 -veined. Lemma surface plumose; hairy below. Lemma hairs 4-5 mm long. Lemma apex lobed; 2 -fid; with filiform lobes; with lobes 1-2 mm long; attenuate; awned; 1 -awned. Principal lemma awn 6-10 mm long overall. Palea lanceolate; 4-5 mm long; 0.66 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous. Anthers 3. Staminodes present; 2 mm long.
    Fruits
    Caryopsis with adherent pericarp.
    Male
    Male inflorescence bisexual similar to female; a panicle. Male spikelets resembling female.
